Abstract In this paper, a permanent magnet synchronous motor current controller based on a sliding mode observer is proposed for improving the robustness to parameter perturbations and load disturbances. By calculating the current deviation decoupling control coupling term, it is found that the deviation decoupling coupling term is simple compared with the conventional voltage feed-forward decoupling. It solves the unsatisfactory decoupling effect of the conventional voltage feed-forward decoupling control. Through the tracking characteristics of the current sliding mode observer, the estimated value of the stator current is taken as a state variable and fed back to the system input terminal to compensate the current error value. This method not only achieves better compensation control for the current loop, but also completely decouples the d and q axis currents, ensuring the dynamic response speed of the system and improving the immunity of the system. The proposed controller is found to be more effective than the conventional controller through simulations and experiments.

Key words： Permanent magnet synchronous motor (PMSM) voltage feed-forward decoupling control (VFDC) current deviation decoupling control (CDDC) current sliding mode observer (CSMO)
